It depends on how you feel about tracking: Sophon declares data used to track you. None of it falls in Apple's most sensitive categories (health, financial, location, contacts or your own content). In total the label lists 4 data types; 29% of cloud storage apps we checked declare tracking.

Built only from the developer's App Store label. It describes disclosure, not tested behaviour.
Sophon's developer reports using identifiers to track you across other companies' apps and websites.
Did Sophon ask for something?
Pick the permission prompt you saw. We compare it with what Sophon's developer declared.
Location is not on Sophon's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
User Content is not on Sophon's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
Contacts is not on Sophon's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
Sophon declares data used to track you, so expect the “Allow to track?” prompt. Tap Ask App Not to Track; the app must keep working without it.
Health & Fitness is not on Sophon's label. That can be fine: data used only on your iPhone does not have to be declared. If the data would need to leave the phone for the feature to work, ask why it is missing.
A permission is what the app can reach on your iPhone; the label is what the developer says leaves it. They answer different questions.
What Sophon collects, explained
| Data type | What it covers | Where to limit it |
|---|---|---|
| Search HistoryNot linked to you | Searches you run inside the app. | Look for a clear-history or private-search option in the app. |
| Contact InfoLinked to youNot linked to you | Your name, email address, phone number or postal address. | Use Sign in with Apple with Hide My Email where offered, and check the app's account and marketing preferences. |
| IdentifiersUsed to track youLinked to youNot linked to you | An account ID, screen name, customer number or a device-level ID such as the advertising identifier. | Settings › Privacy & Security › Tracking: turn off Allow Apps to Request to Track, or tap Ask App Not to Track when prompted. |
| DiagnosticsNot linked to you | Crash logs, launch times, hang rates and energy use. | Settings › Privacy & Security › Analytics & Improvements › Share With App Developers controls what Apple passes on; the app's own crash reporting is separate. |
What Sophon's label means for you
Sophon's label has 1 type under “Data Used to Track You”, 2 types under “Data Linked to You”, 4 types under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.
Tracking is the declaration that most separates apps. It means identifiers from Sophon can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.
None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.
Cloud storage apps exist to move your files off the phone, so collecting user content is expected. What differs is encryption, sharing defaults and what the provider can read. Review automatic camera upload, shared-link expiry and whether client-side encryption is available.
Among the 170 cloud storage apps in our snapshot with a label, 29% declare tracking, 64% collect data linked to you and 24% say they collect nothing. Sophon lists 4 data types, about the same as the average of 3.3 for this group.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.
Settings to check for Sophon
- 1
Tracking
Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.
- 2
Sign-in
When creating an account, Sign in with Apple can give the app a relay address from Hide My Email instead of your real one.
- 3
Lock the app
On iOS 18 and later, touch and hold the icon and choose Require Face ID. Anyone who picks up your unlocked phone then needs your face, fingerprint or passcode to open it.
- 4
Notifications
Settings › Notifications › Sophon › Show Previews: When Unlocked keeps message and account details off the Lock Screen.
Does Sophon track you?
Identifiers. Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker.
Lock Sophon behind Face ID
- Find Sophon on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Sophon now asks for authentication every time it opens.
The lock is an iPhone feature, so it works whether or not Sophon has a passcode of its own. It does not change what the app sends to its developer.

What the label cannot tell you
- A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Sophon sends.
- It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
- Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
- Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
- Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.
